Application filed october 21, 1929*'. serial no. 401,338.

`This invention relates ,to a brake rod silencer. The brakerods which lead to the 'brakes of a'utomobilesfare of considerable length and in the driving ofthe car are subject. to vibration by reason of road shocks. 11n order to hold and guide the rods the same vrpasses through alguide member at a point e ybetweenY the ends ofthe rod and vibration of the. rod Vagainst the sides of the slot in the,y guide member many times produces rattles yand 1 other undesirable noises whichl is the primary object and. purpose of the present vinvention toeliminate. y An understanding of theconstruction which has/been produced for the attainment of the object stated'inay beha'dirom the yfollowing descriptions,

.takenin connection with the accompanying f drawing, in which, d i

Fig. l is avfragmentary side elevation of a chassis side vframe member and the brake rod adjacent the sa1ne,'the silencer construction of my invention being applied thereto and to the brake rod guide-interposed between ther`r chassis frame member and the brake rod.

.F ig. 2 .is an elevation ypartly in section of the construction shown in Fig. l and, f Fig. 3 is a perspective View of the silencer made in accordance with my invention.` b

- Like. reference characters refer to like parts 3o in the'dilierent figures` of the drawing.

` The brake rod 1 is located substantially horizontal a short distance below the adjacent chassis side frame member C and is guided through a slot 2 in the lower end portion of ya guide member 3 connected to an outwardly extending leg l of a bracket attached to the chassis frame member yby means of a bolt 5 which passes through the upper end of the guide member Sand said leg 4. The slot 2 is elongated vertically-and a vibration of the.

middle portion to provide adownwardly eX- tending loopg 'the sidesy of'which are *continued in reverseloops 7 from which two sides SeXtend downwardly anddiverge as` shown. `The, sides 8 areformed'at their lower 55 endsq and continued as spring. coils 9 and from the coils two sections lOvofthe wire extend downwa'rdly and inwardly toward each other andcrossea'ch other "at a point directly be` n low the loop'. The sections '10i at their 60 ends, are turned vupwardly and outwardly at rightangles making the parts ll which terminatein return U-bends or'hooks '12. i In applying thissilencer tothe brake rod, its" guide and chassis frame member, the up-y percentral loop 6 islinsertedupwardly be-r tween the guide'member 3 andthe chassis trame membery so as to bear against thelower edge of arm t. r4One ofthe sections `10,is located at one side ork back ofthe brake rod V1 and the otherl vatV the other side or in front thereof with 'a coil 9 lat each side of the lower end portion of the guide member 3. The sec-v tions 10 are then sprung upwardly so as to hook thehooks 12 overthe brake rod l one 75 at/each-side'offand a short distancefrom the guide member 3 for the brake rod.

In thus applying the silencer the coils 9 are tensioned considerably and thesides 8 and sections 1`O j1sprung outoil shape so that the 80 ei'ect is to' force the `brake rod in a downward direction snugly against the lower end of the slotk 2/in the guide member 3. This insures against vibration of the rod and striking against'the sides of the slotKL which causes S5 rattling noises. e y i a The y construction described is simple to manufactureand easily made and very quickly applied without the use of tools' or employp ment'of skilled labor. Noises comingfrom vibration of the brake rods and striking of the sameagainst the sides of theslot in the guide member, are completely eliminated irrespective of theleXtent of Wearwhich may have occurred-on both the brake rod and the sidesof the slot. The invention is defined in the yappended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I claim): i 1. A device of the class described formed from a single length of spring wire, bent Y at its middle portion to provide adownwardly extending lloop y open at itsl upper side and thence continued to rform reversed loops atl each sideof the first loop, said reversed l loops being continuedto provide downwardly f and outwardly extending sides, spring coils formed at the lower ends of said sides and straight sections extending from saidl coils downwardly and inwardly toward andacross eachother, each of said sections atvv its free. end being bent at right angles for a short distance and then bent' back upon itself to form afU-shaped hook.

" i v v side framemember, abraclet secured to and 2. A'construction of the. class described f Yformed. from a singlevlength of spring wire materialv and bent'at its middleportion to providefktwo downwardly` extending sides spaced apartfrom each other andY integrally connected at their upper ends, spring coils at the ylower ends of, said sides, formed as v continuations thereof, wire sections extend- Y ing; from the coils downwardly and inwardly Vtowardand across each other,.leach -ofs'aid ksections at its free end being bent atjright angles for al short distance and then bent back upon itself to form an open hook. v

v 3. vIn combination, vra motor yvehicle` chassis extending outwardly therefrom, a y guide y ymember pivotally mounted at itsupper end against said: bracket and having detachable connection with said rod'at two points, one at each side of the guide'membensaid spring means being sprungout oflnorrnal yform, Vwhen connected to saidrod thereby subjecting vthe rod toldownward pressure.

4. In combination `with a motor' vehicle chassis side frame member, a. guide member` pivotally connectedv at its upper end to and Y depending from said frame member,` said guide member. having a vertical guide slot at its lower portion, a rod passing through said slot, and a spring device formed from spring wire vmaterial bent to have an upper end portion to engage against the supportfor said guide 'member and having downwardly extending sides with spring coils intermediate the ends thereof, and hook means at the free ends of said sides to engage over said rod and exert `a downwardpressure thereon', said sides of said spring devicebeing gaged-with said rod.
